+ *     whose folder name no release carries ("1989 Pauls Boutique").
+ *  3. + the artist the TAGS name, asked when the folder's artist found nothing
+ *     or the wrong record, and + a try-list that refuses to strip a title down
+ *     to its catalogue number ("Band Of Gypsys (SICP 2643)" → "(SICP 2643)").
+ *  4. + the title without a trailing release-type word ("Willoughby's Beach EP"
+ *     → "Willoughby's Beach"). Both providers require every word of the
+ *     phrase, so the one appended word hid a record each of them holds.
+ *  5. + the FOLDER as a second witness, asked after the record's own claim.
+ *     Tags carry typos the folder does not ("Nonagon Infiniry" on all nine
+ *     files, in a correctly-spelled folder), and until now one wrong tag was
+ *     the only thing any provider was ever asked about.
+ *  6. + the record's TRACK COUNT breaks the tie when one title names several
+ *     MusicBrainz release groups ("Murder of the Universe" is a 21-track Album
+ *     and a 1-track Single, both scored 100, in an unstable order), and a
+ *     provider request that FAILED no longer caches as "nothing found".
+ *  7. The last resort stopped being a title search dressed as a comparison. It
+ *     ranks the artist's WHOLE MusicBrainz discography — complete, where
+ *     Deezer's listing omitted EPs entirely — and decides on every fact the
+ *     scan has: wording, track count, year, the TRACKLIST, and the record's own
+ *     ARTWORK hashed against the discography's covers. A name is one fact about
+ *     a record and the one most often wrong; `Rock Bottom 7"` scores 0.667
+ *     against the release actually called "Rock Bottom / Octopus", and 2 of 2
+ *     on its songs.
+ *
+ *  BUMP THIS AFTER THE RUST BUILD LANDS, never before. Vite hot-reloads this
+ *  constant instantly while the capability it describes lives in
+ *  `metadata::identify_titles`, so bumping it against a running old binary
+ *  makes that binary sweep the negatives and re-stamp the record on screen as
+ *  freshly looked at by code that learned nothing. */
